Carrying Capacity Test
Carrying capacity is a unit of measurement that is used in all sorts of manners. In the study of biology, it looks at the number of people, animals, and crops that a region can support without harming the environment, but it is also a term used to see how many people can fit inside areas like a vehicle or an elevator where volume and weight are a concern. What else do you know about it?

- A.
The maximum number of individuals that can fit into an area

The ability of an environment to accommodate a growing population

The maximum number of species that can co-exist in an area

carrying capacity was not studied in the 1700’s

population size vs. resource use
- B.
Ecologic footprint vs. resource availability
- C.
Population size vs. time
- D.
Resource use vs. time

Increase the number of people the planet can sustain by stimulating plant growth
- B.
Decrease the number of people the planet can sustain by increasing water use
- C.
increase the number of people the planet can sustain by reducing the use of energy for heating
- D.
Decrease the number of people the planet can sustain by reducing land area due to sea level rise
- E.
it is impossible to predict how global warming will affect carrying capacity
- 15.Populations grow exponentially when:

Resources are limited
- B.
Standards of living are high
- C.
Resources are unlimited
- D.
Standards of living are low

it begins to grow exponentially
- B.
It begins to grow logistically
- C.
It stops growing
- D.
It crashes
- E.
It begins to decline slowly
- 18.A population age pyramid is often asymmetrical because:
